Though you may believe that you are your dog’s best friend, they may have canine best friends as well.

Like many mammals, dogs evolved as pack animals, most likely to increase their likelihood of survival. However, that does not mean they do not also form social bonds. You may notice your pet has preferred playmates. They may be less aggressive towards these dogs or more tolerant of their presence. Several factors contribute to this preference, such as playstyle, energy level, and temperament.

Here are a few ways to figure out who your dog’s best four-legged friend is:

They Focus On One Dog

When you take them to the park, daycare, or on playdates with other dogs, you notice they gravitate towards one or two specific dogs, possibly ignoring all other dogs present.

They’re Comfortable

They almost always maintain positive body language around a specific dog. Play bows, loose tail wagging, ears perked up or relaxed are all signs your dog is comfortable.

They Share

They share their bowl, toy, bed, or even YOU with another dog.

Other Species

If you have another pet in the house, your dog may make it a point to spend time in the same general space. These bonds could form with another dog, cat, rabbit, or any other type of pet.

Dogs are social animals but nature, and having a best friend that your dog sees regularly can vastly improve their quality of life. It could contribute to less anxiety and increased comfort and security. It also means elevated levels of tail wags!

Don’t worry, your dog still loves you too, and not just because you’re a consistent supply of treats. Dog and human relationships are a beautifully complex web of love. Your dog not only sees you as a companion but as a protector, and the more time you spend around your dog, the stronger the bond becomes.
